Comcast's Port Blocking Starting To Work
from the slowly...-slowly... dept
After finally admitting they had a problem with zombie machines, and coming up with a relatively intelligent solution (only blocking port 25 on those customers who appear to be spamming), it looks like Comcast is seeing some amount of success in slowing down (what they admit is) the “world’s #1 spammer”: themselves. The new strategy has already cut the amount of Comcast originated spam by 35%. Obviously, there’s still a quite a lot of spam to go, but to cut it that much in just about a month is a good sign.
